Summary
Comparing anatomy representations in the International Classification of Functioning, Disability, and Health (ICF) and International Classification of Diseases 11th Revision (ICD-11) revealed differences in detail and modeling. Reconciliation is needed for a consistent WHO-FIC Foundation.
Area of Science:
- Health Informatics
- Medical Classification Systems
- Ontology Engineering
Background:
- The World Health Organization's Family of International Classifications (WHO-FIC) unifies ICD, ICF, and ICHI into a single foundation.
- Common concepts, particularly human anatomy, require reconciliation across classifications for logical consistency.
- Anatomical representations in ICF and ICD-11 exhibit variations in detail and modeling approaches.
Purpose of the Study:
- To compare anatomical entity representations between ICF Body Structures and ICD-11 Anatomic Detail.
- To identify commonalities, gaps, and discrepancies in anatomical modeling between ICF and ICD-11.
- To inform the reconciliation of anatomical concepts within the WHO-FIC Foundation.
Main Methods:
- Three experts mapped ICF Body Structures to corresponding ICD-11 Anatomic Detail entities (identical, broader, narrower).
- A custom web application facilitated expert mapping and automated identification of equivalences.
- Expert-identified maps and software-generated equivalences were consolidated to establish relations.
Main Results:
- A total of 434 relations were established between ICF and ICD-11 anatomical concepts.
- High inter-observer agreement (93.5%) was achieved for expert mappings.
- ICD-11 generally offers greater anatomical detail than ICF, which tends to group structures.
Conclusions:
- Significant differences exist in anatomical modeling between ICF and ICD-11, with ICF being less granular.
- Discrepancies in anatomical representation necessitate solutions aligned with WHO classification principles.
- This comparative analysis is crucial for harmonizing anatomical data within the WHO-FIC Foundation.

01:20Anatomical Terminology
12.8K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

01:12Regional Terms
9.7K
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to...
